The ethercat commands can be used while your application is running. Try 'ethercat --help' for other options<br>

Subject: [etherlab-users] How to check if all slaves have reached operational state?<br>
<br>
Dear EtherLab users,<br>
After activating the master and starting frame exchange, is there a way to check whether all states have reached operational?<br>
Additional info:<br>
Currently, in my code<<a href="https://github.com/mohse-n/L7N_EtherLab/blob/master/simple_test.c" rel="noreferrer" target="_blank">https://github.com/mohse-n/L7N_EtherLab/blob/master/simple_test.c</a>>, I just send empty frames for long enough (trial and error) so that when I exit the loop, my slaves (servo drives) are in OP state.<br>
I have tried checking the working counter in the loop and exiting from it after the domain's working counter becomes equal to our expected value. However, there is still a small delay after that happens and the second slave reaching operational state.<br>
Best,<br>
Mohsen<br>

Hi Mohsen,<br>
<br>
additionally you can use ecrt_slave_config_state in your application. I call this function plus ecrt_master_state and ecrt_domain_state every other second to check the status of the whole setup.<br>
<br>
Best regards,<br>
Christoph<br>
